| High Light | 0.2mm silicon steel stator laminations ，EV motor rotor laminations ，stator core laminations for electric vehicles | ||
Our Motor Stator and Rotor Laminations are the foundational components for high-efficiency traction motors, specifically optimized for the rigorous demands of the Electric Vehicle (EV) industry. Utilizing ultra-thin 0.2mm silicon steel, these laminations are engineered to minimize eddy current losses at high operational frequencies, directly contributing to extended driving range and superior thermal management.
By leveraging high-speed progressive die stamping and advanced interlocking technologies, we deliver matched sets of stators and rotors with exceptional concentricity and dimensional stability. Each lamination undergoes a precision de-burring process and is treated with high-grade C5 insulation coating to ensure maximum interlaminar resistance. Whether for permanent magnet synchronous motors (PMSM) or induction motors, our lamination solutions provide the high magnetic flux density and low coercivity required for peak automotive performance.
Ultra-Thin 0.2mm Profiles: Significantly reduces core loss at high RPMs, ideal for high-speed EV drivetrains.
Superior Magnetic Permeability: Sourced from top-tier silicon steel mills to ensure consistent B-H curve performance.
Micron-Level Precision: Advanced stamping tolerances of ±0.01mm ensure a perfect air gap and reduced torque ripple.
Innovative Bonding Methods: Support for laser welding, automated interlocking, and "back-lack" (glue bonding) for reduced acoustic noise.
High Power Density: Optimized stacking factors allow for more active material in smaller motor housing volumes.

Our stator and rotor lamination sets are integrated into a variety of high-growth sectors:
Electric Vehicles (EV/BEV): Main propulsion traction motors, range extenders, and integrated e-axles.
Hybrid Vehicles (HEV): Integrated Starter Generators (ISG) and auxiliary motors.
Drones & UAVs: Lightweight, high-RPM motors requiring extreme precision and low mass.
Industrial Servo Motors: High-precision robotics, CNC machine tools, and automation equipment.
Medical Devices: High-speed surgical tools and laboratory centrifuges requiring silent operation.
We provide a "one-stop" customization service from prototyping to mass production:
Bespoke Geometry: Support for complex slot shapes, skewed rotor designs, and internal cooling channels.
Prototyping Services: Rapid laser cutting or CNC machining for design validation before investing in hard tooling.
In-House Tooling: Dedicated mold department for developing high-precision progressive dies.
Material Optimization: Expert guidance on selecting the right steel grade to balance cost and motor efficiency.
DFM Analysis: Design for Manufacturing feedback to optimize lamination geometry for cost-effective stamping.
Magnetic Simulation: Support for FEA (Finite Element Analysis) data to predict motor core performance.
Quality Inspection: Comprehensive reporting including CMM dimensional checks and magnetic properties testing.
Rust Prevention: All laminations are treated with VCI (Volatile Corrosion Inhibitor) oil and vacuum-sealed.
Custom Cushioning: Specialized foam inserts or plastic trays prevent damage to sensitive stator teeth during transit.
Export Standards: Shipped in IPPC-certified heat-treated wooden crates with heavy-duty strapping for sea and air freight.
Q: Why is 0.2mm silicon steel preferred for EV motors?
A: Thinner laminations reduce eddy current losses, which increase exponentially with frequency. As EV motors run at very high RPMs, 0.2mm steel helps maintain efficiency and prevents overheating.
Q: Can you provide matched stator and rotor sets?
A: Yes, we specialize in producing matched sets to ensure consistent air gaps and optimized magnetic flux paths between the stator and rotor.
Q: Do you offer back-lack (glue bonding) technology?
A: Yes, we provide bonded lamination stacks which offer superior noise, vibration, and harshness (NVH) characteristics compared to traditional welding or interlocking.
Q: What is the typical lead time for an automotive-grade project?
A: Samples via laser cutting typically take 7-10 days. Mass production tooling and initial parts usually require 6-8 weeks.
